On a sustained AHHHH, the duty-cycle is around 35%. Sentences have a
duty-cycle of roughly 15%. This is why so many ssb amplifiers get by
with a fairly small HV transformer. In order to be able to see this, one
needs an oscilloscope to compare the peak v drop across the plate/anode
meter shunt R with the plate/anode meter reading.
good question, Hank.
